Also cannot find anything on Elizabeth/Betsy after 1861. It could be possible she was sending money to the Jones family for his keep. Parish relief did not pay out easily if there was someone responsible, why was he not in the workhouse? Although his surname is Jones? By 1871 he would have been able to earn himself.
